Incineration continued alternative

Environmental impacts Continued impact from existing conditions Would be some migration of contaminant pluma as part of attenuation process Vapor extraction may affect air quality and odors although it will meet emission standards would be aquifer drawdown during groundwater extraction See Alternative 3 fixation may also affect air quality and produce odors Incineration may affect air quality by producing odors, although if will meet emission standards... 

We do not consider on-site, mobile incinerators for the following reason. Mobile incinerators are currently licensed to burn only PCB contaminated liquids, but EPA officials anticipate final approval to bum PCB contaminated solids by 1986 [ 4 ]. Hence, we cannot, concentrate the extract any further if a mobile incinerator were to be used. Tbe mobile incinerators appear to have a capacity of about 3.6 x 10 kg/day [5 ]. To incinerate the concentrated extract produced by solvent extraction process, in excess of 2700 days of continuous operation of a mobile incinerator would be required. To complete the incineration in a single working season (see below), many mobile incinerators would be required. The cost of a mobile incinerator has been estimated to be about 2 million dollars [6 ]. Applying the criteria of completing the cleanup in one season (this point will be discussed later), it appears as though mobile incinerators are unlikely to be economically advantageous. Hence, we eliminate this alternative. 

The authors had already conducted the laboratory scale study and the preliminary pilot plant study, and proposed that "drying-pyrolysis process" (pyrolysis followed by indirect steam drying of dewatered sludge cake) (Fig,-i) could be one of the most economical and feasible alternatives for conventional incineration process. The authors have further conducted the feasibility study on a continuous system of "drying-pyrolysis process to evaluate the performance of the process in pilot scale, and to demonstrate its effectiveness as a thermal processing of sewage sludge. This paper presents the results of this pilot plant study. 

The NAS National Research Council endorsed the Army s disassembly and high-temperature incineration process for disposing of chemical agents and munitions. The council also recommended that the Army continue to store most of the chemical stockpile, dispose of the M55 rockets, and analyze alternative methods for disposing of the remaining chemical stockpile. 

A growing area of concern is how to conscientiously dispose of products or their components. Black Decker avoided significant landfill costs and made money by seUing recyclable commodities. When there are no alternatives except disposal, the product or material needs to be appropriately scrapped. In an era of environmental concern (which will continue to grow and drive marketplace decisions), companies should take proactive action to develop environmentally sound landfiU or incineration programs. Not only will this allow favorable consumer reactions, but it may forestall government regulation and control. 

General Finding 15. The Dialogue process for identifying an alternative technology is likely to reduce the level of public opposition to that technology. The committee believes that the Dialogue has been and continues to be a positive force for public acceptance of alternatives to incineration.
